Title: Method of recovery of noble metal from metal carrier catalytic converter
Inventor: KASUYA MASAYUKI
IPC: B09B3/00
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a method of recovering noble metal in a metal carrier without using chemical solutions and liquid nitrogen and further without breaking a honeycomb body. SOLUTION: A metal carrier of a metal carrier catalytic converter is heated to the high temp. and then rapidly cooled by water cooling, by which a wash coat layer containing noble metal is peeled off from the metal carrier. It is preferable to regulate the hating temp. of the metal carrier to 800-1400 deg.C. Moreover, it is desirable that the cooling of the metal carrier by water cooling is performed by injecting water into the gass passage of the honeycomb body of the metal carrier, and further, it is more desirable to regulate the amount of water to be injected into the honeycomb body to 10 to 50 l/min.cm<2> per cross-sectional area of the honeycomb body.

Abstract: PURPOSE:To improve reliability by a construction wherein a state of gas leak is prepared artificially when it is judged that there is no valve leak abnormality in first and second cutoff valves, and a self-diagnosis as to whether a leak check function of an apparatus is normal or not is executed. CONSTITUTION:When it is judged that there is no valve leak abnormality in first and second cutoff valves 1 and 2, a controller 10 stops excitation of an electromagnetic proportional coil 26 to release a pressurizing operation, makes the valves 1 and 2 open to supply a gas into a chamber, an object of detection, and then makes the valve 2 close to maintain the pressure in the chamber. Next, the valve 2 being opened with the valve 1 closed, reduction of the pressure in the chamber, the object of detection, is started and a state of gas leak is made to occur forcibly. When this state of gas leak is detected by a pressure sensor 30, the controller 10 judges a leak check function of an apparatus to be normal if a signal from the sensor 30 shows detection of the lowering of the pressure and presence of the valve leakage abnormality.

IPC: G11B7/085
Filed: 1988-12-28
Abstract: PURPOSE:To omit the use of an exclusive reference speed signal generating circuit by changing the count value of the track crossing pulses in response to each speed. CONSTITUTION:The track error signals are inputted to a waveform shaping circuit 6 and turned into the track crossing pulses after shaping the waveforms. These crossing pulses are sent to a counter 1. The counter 1 counts the received track crossing pulses and sends the count value to a numerical comparator 3. The comparator 3 compares the value stored in a register 2 with the value of the counter 1 and informs the coincidence of both values to a microprocessor 4 when this coincidence is secured. At the same time, a reference speed in response to the head moving distance is outgone to a D/A converter 5. Then a head moving means 20 moves an optical head in accordance with the obtained reference speed. Thus it is possible to change the head moving speed in response to the head moving distance without using any exclusive circuit.
